building a pretty healthy 406 for my mud truck, any suggestions on camshaft selection criteria?? as far as truck cams/race cams/etc... should it be like a circle track grind? maintaining pretty high rpm instead of a "rpm range"... little input from some veterans would be appreciated! thanks, david

Comp Cams does have some grinds they claim are for Mud Trucks, might want to look at that. General rule of thumb, mudding is acting more like a Bracket Racer than a Circle Track racer - you should be looking at Drag Race cams, exact cam will depend on weight, gearing, tire size and compression.
